Here's v0.02 for those intrepid testers who want to see what their build is actually doing rather than watching a wall of mostly uninteresting text scroll by really fast.

With this script, you can actually spot the warnings.

The previous version got really confused by what "make dep" did in response to kernel module versions being switched on (but only after a fresh untar, or after running make mrproper). I've now taught it more about the evils of make dep, so it's less confused, but I wouldn't call the cleaned up version of the output pretty... (I'm not too worried: Kieth Owens' new build makes make dep go away completely. I now know a lot more about why this is a good thing.)

Just throw the attached file in the scripts directory. The script to test this still goes:

And it still requires python 2, but you cml2 testers should have no trouble with this. :)

I'm working on the curses frontend to replace the above script. (The frontend is about half the point of the exercise, cleaning up text mode is just a nice way to test it), but I've got paying work standing between me and that for a bit, so it'll be a few more days... :)
